GLGETTEXPARAMETER(3G)							    GLGETTEXPARAMETER(3G)

NAME
       glGetTexParameterfv, glGetTexParameteriv - return texture parameter values

C SPECIFICATION
       void glGetTexParameterfv( GLenum target,
				 GLenum pname,
				 GLfloat *params )
       void glGetTexParameteriv( GLenum target,
				 GLenum pname,
				 GLint *params )

PARAMETERS
       target  Specifies  the  symbolic name of the target texture.  GL_TEXTURE_1D,GL_TEXTURE_2D,
	       and GL_TEXTURE_3D  are accepted.

       pname   Specifies the  symbolic	name  of  a  texture  parameter.   GL_TEXTURE_MAG_FILTER,
	       GL_TEXTURE_MIN_FILTER,		GL_TEXTURE_MIN_LOD,	      GL_TEXTURE_MAX_LOD,
	       GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL, GL_TEXTURE_WRAP_S, GL_TEXTURE_WRAP_T,
	       GL_TEXTURE_WRAP_R,      GL_TEXTURE_BORDER_COLOR,      GL_TEXTURE_PRIORITY,     and
	       GL_TEXTURE_RESIDENT are accepted.

       params  Returns the texture parameters.

DESCRIPTION
       glGetTexParameter returns in params the value or values of the texture parameter specified
       as  pname.   target  defines  the  target texture, either GL_TEXTURE_1D, GL_TEXTURE_2D, or
       GL_TEXTURE_3D to specify one-, two-, or three-dimensional texturing.   pname  accepts  the
       same symbols as glTexParameter, with the same interpretations:

       GL_TEXTURE_MAG_FILTER		  Returns the single-valued texture magnification filter,
					  a symbolic constant. The initial value is GL_LINEAR.

       GL_TEXTURE_MIN_FILTER		  Returns the single-valued texture minification  filter,
					  a    symbolic    constant.   The   initial   value   is
					  GL_NEAREST_MIPMAP_LINEAR.

       GL_TEXTURE_MIN_LOD		  Returns the  single-valued  texture  minimum	level-of-
					  detail value.  The initial value is -1000.

       GL_TEXTURE_MAX_LOD		  Returns  the	single-valued  texture	maximum level-of-
					  detail value. The initial value is 1000.

       GL_TEXTURE_BASE_LEVEL		  Returns the single-valued base  texture  mipmap  level.
					  The initial value is 0.

       GL_TEXTURE_MAX_LEVEL		  Returns  the single-valued maximum texture mipmap array
					  level.  The initial value is 1000.

       GL_TEXTURE_WRAP_S		  Returns the single-valued wrapping function for texture
					  coordinate s, a symbolic constant. The initial value is
					  GL_REPEAT.

       GL_TEXTURE_WRAP_T		  Returns the single-valued wrapping function for texture
					  coordinate t, a symbolic constant. The initial value is
					  GL_REPEAT.

       GL_TEXTURE_WRAP_R		  Returns the single-valued wrapping function for texture
					  coordinate r, a symbolic constant. The initial value is
					  GL_REPEAT.

       GL_TEXTURE_BORDER_COLOR		  Returns four integer	or  floating-point  numbers  that
					  comprise  the RGBA color of the texture border.  Float-
					  ing-point values are returned  in  the  range  [0,  1].
					  Integer  values are returned as a linear mapping of the
					  internal floating-point representation  such	that  1.0
					  maps	to  the  most  positive representable integer and
					  -1.0 maps to the most negative  representable  integer.
					  The initial value is (0, 0, 0, 0).

       GL_TEXTURE_PRIORITY		  Returns  the	residence  priority of the target texture
					  (or the named texture bound to it). The  initial  value
					  is 1.  See glPrioritizeTextures.

       GL_TEXTURE_RESIDENT		  Returns the residence status of the target texture.  If
					  the value returned in params is GL_TRUE, the texture is
					  resident in texture memory.  See glAreTexturesResident.

NOTES
       GL_TEXTURE_PRIORITY and GL_TEXTURE_RESIDENT are available only if the GL version is 1.1 or
       greater.

       GL_TEXTURE_3D,	  GL_TEXTURE_MIN_LOD,	  GL_TEXTURE_MAX_LOD,	   GL_TEXTURE_BASE_LEVEL,
       GL_TEXTURE_MAX_LEVEL, and GL_TEXTURE_WRAP_R are available only if the GL version is 1.2 or
       greater.

       If an error is generated, no change is made to the contents of params.

ERRORS
       GL_INVALID_ENUM is generated if target or pname is not an accepted value.

       GL_INVALID_OPERATION is generated if glGetTexParameter is executed between  the	execution
       of glBegin and the corresponding execution of glEnd.
